Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Geology): "SHATTERED QUARTZITE IS SEAMED WITH STRINGERS OF QUARTZ AND IRON OXIDE CARRYING A LARGE AMOUNT OF FREE GOLD. HERE AND THERE ARE SMALL BODIES OF PYRITE AND GALENA IN THE FRACTURE PLANES OF QUARTZITE AND MINUTE STRINGERS OF GRAY METALLIC MINERAL SAID TO CONTAIN BISMUTH. ASSAYS SHOW SILVER...BY WEIGHT EQUAL TO GOLD. THE QUARTZITE NEAR THE ORE IS IMPREGNATED WITH PYRITE AND LOCALLY DECOMPOSED TO A SOFT WHITE CLAYLIKE SUBSTANCE SAID TO CARRY HIGH VALUES IN GOLD."-EMMONS.
Comment (Deposit): IN 1907, HIGH-GRADE GOLD ORE WAS DISCOVERED IN HILLTOP CANYON, BEGINNING RUSH TO THE AREA. HILLTOP MILLING AND REDUCTION CO. BUILT A 10-STAMP MILL IN ABOUT 1910; CONVERTED IN 1914 TO A CYANIDATION MILL. HILLTOPS INDEPENDENCE MINES WERE LOCATED IN 1906. PAINCIPAL PRODUCTION FROM HILLTOP DISTRICT WAS FROM 1912 TO 1921. TOTAL PRODUCTION FROM THE DISTRICT FROM 1902 TO 1936 WAS $701,855, MAINLY IN SILVER AND GOLD, WITH SOME COPPER AND LEAD. ; INFO.SRC : 1 PUB LIT
